4 外墙外保温和饰面系统的使用历史 EIFS HISTORY
二十世纪四十年代 - 矿棉覆以水泥抹灰作为保温系统在瑞典得到应用 1940’s - Wall cladding used in Sweden - mineral wool coated with cement/lime plaster 二十世纪六十年代 - 发泡聚氨酯覆以下埋增强纤维网的面涂作为保温系统在西德得到应用 1960’s - West Germany - rigid polystyrene foam, mesh, and reinforced coatings Frank Morselli 创建了专威特外保温和饰面系统 Frank Morselli founded Dryvit Systems, Inc. - with design of systems as we know them today.

6 EIFS WALL ASSEMBLY 底材 SUBSTRATE: 夹板，外墙装饰板，耐水石膏及水泥砂浆墙面。Plywood, Oriented Strand Board, Water Resistant Gypsum Sheathing, and Masonry. 胶粘剂 ADHESIVE: 水泥或非水泥基；把保温材料粘结在底材上。Cementitious or Non-cementitious; used for adhering insulation board to the substrate. 抹面胶浆BASE COAT: 水泥或非水泥基；增强耐水性和面涂与保温材料的粘结力；中间埋入玻璃纤维网布以提供强度和抗冲击。Cementitious or Non-cementitious; provides water resistance and adhesion; fiberglass mesh is embedded for strength/impact resistance. 饰面 FINISH COAT: 装饰涂料；色彩丰富，立体饰面效果，抗开裂，不褪色不黄变 Decorative coating; tintable, comes in various textures, resists cracking, fading and yellowing. Most common substrates in North America are DensGlas Gold, made by Georgia Pacific or OSB Plywood.

7 外墙外保温结构类型 EIFS ASSEMBLY TYPES
无排水 EIFS without Drainage 标准常用系统，保温材料直接粘在底材上 Standard system, insulation board flush to substrate 用于实心砖墙，水泥砂浆墙面较多 Common on Solid Block, Masonry wall 有排水 EIFS with Drainage 保温材料背后有沟槽，便于湿气排出 Grooves on back of insulation board to allow drainage of incidental moisture. 注意并非水流Not a waterfall! 通常用于木结构或者空心墙体建筑 Common on wood frame construction or any wall assembly where there is a wall cavity space. EIFS with Drainage is a system designed to allow incidental moisture that does get behind the insulation board to drain out the bottom of the EIFS assembly and away from the total wall assembly. The problem with a standard non-drainage system is not the system itself, but instead poor construction practices in other areas of the wall assembly. For example, a standard non-drainage EIFS assembly could be installed flawlessly, however, if flashing, especially around windows and dormers, is not done properly, water could get behind the EIFS assembly. Without a drainage plane, it is very difficult for that moisture to get out. In wall assemblies that have cavities – stick built frame construction, for example – poor construction practices could allow water into that cavity. So, though the culprit was never the EIFS itself, trial attorneys were effective is swaying court decisions to take a stance saying basically that even though EIFS didn’t cause the initial water intrusion, the EIFS industry should have a system that allows that moisture a way to get out.

18 抹面砂浆和胶粘剂 Basecoats and Adhesives
通常胶粘剂和抹面砂浆是相同配方 Basecoat & Adhesive are often the same 主要以水泥基为主Usually cementitious 可以粘结在不同底材上 Adhesion to variety of substrates 木材，复合材料，石膏，水泥砂浆 Wood, Composites, Gypsum, Masonry 抹面砂浆中埋入玻璃纤维网布 Mesh embedded into basecoat 为聚苯板提供抗冲击 Provides impact resistance to EPS 耐水Water Resistance 使用100%纯丙烯酸原料获得最佳性能 Use 100% Acrylic Polymer for Optimum Performance

20 EIFS andAggregate Finishes Binders for Basecoats and Adhesives
用于水泥抹面砂浆和胶粘剂的乳液 EIFS andAggregate Finishes Binders for Basecoats and Adhesives SF-016 EI-2000 多用途，耐沾污 Cement compatible, multi-purpose, Dirt Pick-up resistant (DPR) MFFT =8oC Tg = 13oC % Solids = 46-47 高性能多用途 High Performance Basecoat and Adhesives MFFT =1oC Tg = 0oC % Solids = 50 MC-76 was developed for better high temperature pot life. MC-1834 is the low odor version of MC-76. These three are standards in the cement modifier area. They are sometimes used in EIFS basecoats. EI-2000 is the largest volume North America product for EIFS at ~ 60MM lbs per year. EI-2000 is essentially AC-235 type without the adhesion promoter, and has 0.3% benzophenone post-added for DPUR. EI-3317 is Quick-Set technology. It is used in Europe but never caught on in North America. The North America customers felt that it gave surface dry but they did not like that the bulk of the coating was still “wet.” This technology is much more popular in German market. EI-8764 (AC-264 renamed for EIFS market) is sometimes used when customer perceives they need some extra adhesion vs. EI For example, some Canadian customers switch from EI-2000 to EI-8764 in the “shoulder season” when it is cool and damp to get better wet adhesion to basecoat. APR-968LO RHOPLEX MC-76 性价比高 Economy Basecoat/Adhesive MFFT=11oC Tg= 5oC % Solids = 47.5% 适合喷涂施工 Sprayable cement applications MFFT=10-12oC Tg= 5oC % Solids = 47-48
